ATTACHMENT FOR PUMPS.

Application filed April 52 To all whom it may concern Be it known thatW6, EUGENE Prnnnn Oo- 'rwn TRUD'HL and AUGUSTE ZIANI, respectirely asubject oi the King of Great Britain and a citizen of the FrenchRepublic, residing; at Montreal, Province of Quebec, lloininion ofCanada, have invented certain new and useful Improvements in Attachmentsfor Pumps; and We do hereby declare that the following is a full, clear,and exact (inscription of the same.

The present invention relates to improvements in attachments for pumpsor the like, and the main object or: the invention is to device a simpleand etl'ective means to automatically stop a pump When a certain leveloi fluid has been obtained in a tank.

The device herein disclosed adapted to shilit the driving belt of thepump from the iast to the loose pulley, or to cut out the electriccurrent actuating the operating inoior oi the pump.

The invention consists essentially in derising an arrinigeinent oi partswhereby a float by rising or falling inside a tank Will operate a.controller bar which, in turn acts to shiiit the belt 'or throw themotor switch as the case may be. a

The invention Will be better understood with the aid of the accompanyingdrawings in which: a

Like numerals of reference indicate corresponding parts of each figure.

in the dravings 1 represents a tank having at one end a Water inlet pipe2, and 3 is a bracket on the upper end oi. said tank in which suitablyjournaled a pulley 4t, 5 and 6 are pulleys suitably secured in thebottom of said tank, and 7 is a pulley secured to the inner side of saidtank adjacent its upper edge.

At any convenient place, near or away from said tank may be secured abase board 8 Which is provided with the pulleys 9 and 10, and 11. is acable adapted to pass over an enlarged trout elevation of Specificationof Letters Patent.

said pulleys et, 9, 10, T, (l and 5, said cable being secured at one endto the top of a float 12 having depending sides 13, preferably ofinverted cup shape, and provided at its top with an air chamber 14:. Theother end of said cable 11. secured to the upper 1nernheir 15 ot atoggle, l member 15 being provided with a lOl slot 16 in which Works apin 17 secured to the board 8, one end oi? said member 15 beingprovided. with a hook like or curved portion 18 having a hole 19therein. The lower llltll'llllBl' 20 of the toggle is pivotally securedto the lower end oi the upper member 15 by means of the pin 21 and hasat its other end a hook-like or curved portion in which is provided acentral hole and EH: is a spiral. spring loosely secured at oppositeends in the holes 19 and 23 to urn-orally hold the toeglo member; invertical position. end of said :lnt-nnber 2t) pivotally secured on thepin onthe base-board S. and 2-6 is a horizontally disposed controllerbar inter- "i said members 15' and f2 and provided with a. longitudinalslot 2? which is adapted to engage the pin 21. At one end oi? said bar26 is pivotally connected a link 28 which is adapted to pass tl'lroug'ha bracket Eli) secured to the baseboa rd 8. T he link 28 is providedwith two downward depoi ng lugs 30 adapted to engagjie the drivin g lolloi? the pinnp.

A. cable 31 suitably secured at one end to the bottom oi? the airchamber 1.4; of the heat and passes around the pulleys 5, 6, and 7, saidcable being seem-ed at its other end to the toggle member 15 on theopposite side Olli the cable ll-so as to exert an opposite,pullingaetion.

It will readily be seen from the foregoing description that immediatelyon lowering or rising oil the Water level in the tank 1 according to themanner in which the device has been adjusted, the cables 11 or 31 willexert av pulling action on the toggle due to the upward or downwardmovement of the float which follows the water level. According to thedrawings the device is so arranged that if the Water level drops in thetank 1 the float Will naturally exert a pulling action on the cable 11Which will naturally pull the toggle 15, 2O gradually or suddenly as thecase may be past the vertical position into the dotted line ositiondisclosed in Figs. 1 and 2 of t e drawings The lower thereby shiftingthe controller bar 26 and link 28 toward the right. The lugs 30 whichengage the belt will carry the same onto the driving pulley, therebyputting the pump into operation and thus filling the tank to therequired level.

The float which will gradually rise with the liquid in the tank willeXert a contrary actionv on the cables, that is: the cable 31 will bepulled back carrying with-it the t0ggle 15,20 and bar 26 which willshift the driving belt onto the loose pulley when the predeterminedlevelhas been reached.

In Fig. 3 oi the drawingsis illustrated a modification of the invention,according to which an electric switch 32, which controls the supply ofcurrent to the motor is actuated by the movements 01"? the controllerbar 2-8, the handle of which is pi votally connected to the bar 28 by,n'ieans of the link In this case, the pump 1s connected directly to themotor and no driving belt is used.

34; and 35 are weights provided on the cables ,11 and 31 for taking upthe slack of said cables and thus imparting an immediate action on themember15.

It will readily be understood that the construction of this device maybe altered or modified according tothe existing conditions withoutdeparting from the scope and spirit of the invention. It is evident thatthe device can be easily adapted for other purposes than those specifiedin the foregoing description.

lVhat we claim asour invention is:

1'. In a device of the character described. the combination of a togglecomprising a pair of pivot-ally connected and supported members; amovable controller pivotallv connected to the confronting inner ends ofsaid members to be shiftedjthereby; a tension spring connected atopposite ends to the outer ends of said members; and means distinct fromsaid controller for exerting a direct pulling action upon said membersagainst the tension of said spring to operate the toggle.

2. Ina-device of the character described. the combination of a. togglecomprising -a pair of pivotally connected and supported members; anendwise mova-ble controller bar pivotally connected at one end to theconfronting inner ends of said members to be shifted thereby; aten.--:i'.)n spring connciflvd at opposite ends to the outer ends otsaid members; and means distinct from said bar for pulling said membersin either dircrtion against the tension of said spring to operate l hetoggle.

3. in a device of the character described. the combination of a toggleupper and lower members and a pivot pin conmiviing their confrontinginner ends, the upper member having a longitudinal slot; a movablecontroller having av longitudinal slot in which said pin works; upperand lower 1)lll, f pivotally supporting the outer ends oi the respectivetoggle members the upper pin projecting through the slot in the uppertoggle member; a tension spring connected :d (mposite ends to the saidouter ends of the toggle membcrs; and means for pulling said togglemembers to one side no as to operate said controller.

4. In a device of the character described,

the combination of a tank and. means For supplying fluid thereto; afloat in the rank: a toggle mounted adjacent the tank; a con troller forthe fluid.-sup lying means con-- nected tosaid toggle to be operatedthereby; and flexible connecting means between said toggle and saidfloat at opposite sides thereo l to operate the former and thereby theiontrollerconsequent upon the rising and talling movements of the floatdue to variations in the level of the fluid in the tank. In a device ofthe character de -a'ibcd. the combination of a tank and means to;-supplying fluid thereto; a float in the tank; a. toggle mounted adjacentthe tank; an endwise-mova-ble bar for controlling the fluidsupplyingmeans connected at one end to the toggle to be operated thereby; andcable connections between said toggle and said float to operate theformer and thereby shift the controller bar consequent upon the risingand falling movements 01 the float due to variations in the level of thefluid in the tank.
